Redco™ Switchblade (Belt Scraper / Belt Cleaning)
Redco™ Switchblade™ is an innovated new conveyor belt cleaning system that replaces traditional scraper blades and belt wipers. The patented design uses a re-usable mounting base and a replaceable scraping blade section that can be quickly changed during routine maintenance. The advantage of Redco™ Switchblade™ extends beyond the design, as field trials show it outlasts the competition by more than 3x in head-to-head competition and the innovative blade geometry starts cleaning your belts faster, with less “break-in” period.
Available in a wide range of belt sizes, Redco™ Switchblade™ replacement blades are available in bulk 120” long sections for improved yield and custom cutting on site. Supercharge your belt cleaning system with Redco™ Switchblade™.

Redco™ Truck Charge Hopper & Discharge Chute Liner
Mixing concrete is a difficult process, and is especially taxing on your mixing equipment. In recent years, the value of lining equipment has become readily apparent; however, if you’re not using the proper lining materials, lining your equipment can cause excessively long shut-downs.
Urethane liners resist sticking and build-up inherent with rubber and steel type liners, provide easier cleanup, and wear longer than steel.

  • Fast, Bolt In Installation
  • No Seams to Disrupt Flow or Collect
  • Provides easier loading of Mixer and less time at the slump rack.
  • Lightweight and outperforms steel.
  • Economical—protects metal hopper and main chute against wear.

Redco™ Urethane Pan Mixer Liners
Protect your pan liner and reduce maintenance cost with a Redco™ Urethane pan mixer liner.

  • Ease of clean-up between batches (breaking loose dried concrete)
  • Reduce or eliminate sticking and buildup
  • Can outlast steel liners by 2 – 4 times
  • Reduces noise levels
  • Reduced downtime and maintenance

Redco™ Urethane Wear Pads
Redco™ Urethane Screw Conveyor Flight Wear Pads are the solution to the abrasion problems inherent in screw conveyor applications. The advantages to urethane wear pads are:

  • Urethane won’t rust or corrode
  • Lightweight = easy to install with less wear on equipment
  • Redco™ urethane classifier shoes will return to their original shape if bent or distorted
  • Available in a variety of styles and replacement sizes

Pads & Bumpers
Redco™ Pads & Bumpers
Redco™ Pads & Bumpers Constant banging and scraping will wear out equipment prematurely. Redco™ Plastics are engineered for the toughest applications to absorb impact and prolong equipment life. We have developed numerous parts for trucks and shovels such as:
Redco™ Body Pads, which have been designed to replace traditional rubber pads, provide longer wear life and don’t permit the impregnation of rocks. The pads bolt or weld directly to the bottom of the truck box to protect the frame from shock, vibration, and wear.
Redco™ Urethane Bumpers, which are available in many custom sizes, protect the truck body from banging ladders, wheel chocks, etc. while the truck is in motion.
